Answer 1

I'm using Bootstrap 4 and Dennis Puzak's solution does not work for me.

The next solution works for me

.form-control::placeholder { color: white;} /* Chrome, Firefox, Opera*/
:-ms-input-placeholder.form-control { color: white; }  /* Internet Explorer*/
.form-control::-ms-input-placeholder { color: white; }  /* Microsoft Edge*/
